TLDR: cant recommend, there are other better rebus puzzles out there.
I just wrote a review which failed to upload because I forgot a title!?!!? Really?? To annoying to rewrite it but the gist of it was that other rebus puzzles are more challenging and better made. Often takin days and friends help to solve. With the result: us thinking "wow that is brilliant and simple, how didnt we see it sooner".
With this app I just thought OMG that is stupid, really?
The puzzles with letters in them are too easy. And the ones without often i only got with the hint, by solving the hint rather than it helping solve the picture. The coffee cup, which is actually tea, with no teabag, has a different colour saucer. Assuming that is like that intentionally or that the castle is deliberate incomplete but then neither relate at all to the answer. Why do it then?
